Device Overview

Summary

LPC47M182 is a 3.3V (5V tolerant) PC99a/PC2001 compliant Advanced I/O controller for Desktop PCs. It’s LPC interface supports LPC I/O and DMA cycles. The true CMOS 765B core provides 100% compatibility with IBM PC/XTTM and PC/ATTM architectures. The parallel port is compatible with IEEE 1284 EPP and ECP.

The product incorporates sophisticated power control circuitry (PCC) which includes support for keyboard and mouse wake up events as well as PME support. 
The PCC supports multiple low power-down modes.

The Motherboard Glue logic includes various power management logic including generation of nRSMRST, Power OK signal generation, 5V main and standby reference generation. There are also three LEDs to indicate power status and hard drive activity. The translation circuit converts 3.3V signals to 5V signals.

SMBus main power well to resume power well isolation circuitry, included. The I/O Address, DMA Channel and hardware IRQ of each logical device in the LPC47M182 may be reprogrammed through the internal configuration registers. There are up to 480 (960 for Parallel Port) I/O address location options, a Serialized IRQ interface, and three DMA channels.
